Engineering Selection Recommendations

All identified substitute parts maintain active product status and full ROHS3 compliance. Selection between DF22B-3S-7.92C, DF22-3S-7.92C(28), DF22L-3S-7.92C(28), and DF22R-3S-7.92C(28) is determined by color requirement and inventory availability. The primary distinction among these parts is housing color: white (DF22B and DF22), red (DF22L), and black (DF22R). All parts are manufactured by Hirose Electric Co., Ltd., and carry identical electrical and mechanical specifications. Selection should be based on application color coding requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can DF22-3S-7.92C(28) be used as a direct replacement for DF22B-3S-7.92C?

A: Yes. Both parts are white-colored 3-position receptacle housings with identical electrical and mechanical specifications, including pitch, termination method, fastening type, and operating temperature range. The primary difference is the base product number designation.

Q: What is the significance of the color variants (DF22L and DF22R)?

A: Color variants allow for visual circuit identification and system organization. DF22L provides red housing, while DF22R provides black housing. All color variants maintain identical connector specifications and are functionally interchangeable where color coding is not a design constraint.

Q: Are contacts included with these connector housings?

A: No. All DF22 series housings are supplied without contacts. Contacts must be sourced separately and crimped into the housing according to Hirose specifications.

Q: What does the "(28)" designation in DF22-3S-7.92C(28) indicate?

A: The "(28)" designation is part of the manufacturer's part numbering system. It does not affect the electrical or mechanical compatibility of the connector housing.

Q: Can these receptacle housings be used with different pitch contacts?

A: No. These housings are designed exclusively for 0.312" (7.92mm) pitch contacts. Using contacts with different pitch specifications will result in improper mating and connector failure.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate within the range of -55°C to 85°C, ensuring consistent thermal performance across the DF22 series.
